Metallic Minerals Announces Surface Samples up to 12,000 g/t Silver from Keno Summit Targets on Keno Silver Project in the Yukon Territory

Vancouver, December 4, 2017 - Metallic Minerals Corp. (TSXV: MMG) (OTC Pink: MMNGF) ("Metallic Minerals" or the "Company") is pleased to announce initial exploration results from its 2017 field program, including trenching and surface sampling at the Keno Summit area of its 100% owned Keno Silver Project, in Canada's Yukon Territory. The Keno Silver Project is located in the historic Keno Hill Silver District; a region which has produced over 200 million ounces of silver and currently hosts one of the world's highest-grade silver resources. Further data analysis on the project is in process and additional results from the 2017 program, which included diamond core drilling at the Caribou/Duncan and Homestake targets, are anticipated in the coming weeks

During Metallic Minerals' inaugural program at the Keno Silver Project, the Company conducted field investigations, including detailed stratigraphic mapping of trenches and outcrops, surface sampling, satellite photogrammetry, geophysical surveys, soil sampling, trenching and diamond drilling. Twelve targets were prioritized for initial follow-up work, with three of these advanced to the drill targeting stage which commenced in September. Trenching was completed on five target areas which had identified prospective areas through soil sampling and geophysics. The trenching was intended to confirm the presence of significant bedrock mineralization that could be advanced to drill-ready status and was conducted primarily in the Keno Summit area, namely at Gold Hill, Bounty, Caribou, Faith/Divide and Homestake targets (see Figure 1). A total of approximately 0.5 kilometers of trenching was completed in 18 locations as a series of linear trenches or pits. The trenches yielded valuable stratigraphic information, with particularly noteworthy results returned from the Gold Hill and Bounty target areas where significant new bedrock mineralization was exposed at surface following initial soil and rock sampling.

Greg Johnson, CEO & Chairman stated, "We are very pleased with the results seen thus far from the inaugural field exploration program at our Keno Silver Project, as they have validated our exploration methodology and clearly demonstrate the potential for additional new discoveries in this historic district. After undertaking a comprehensive review of historic and modern exploration information, we identified over 40 potential targets, prioritizing the top 12 for follow up in 2017. Our strategy has been to utilize the same systematic exploration approach that has resulted in new significant discoveries in the district by Alexco Resource Corp. The 2017 program specifically focused on areas hosting historic production, where high-grade silver occurs in the preferred Keno Hill Quartzite and Greenstone host rocks along the key mineralized structures that trend across the district. Results from the Keno Summit target areas have been very promising, with additional results from diamond drilling at the three most advanced targets at Caribou/Duncan and Homestake expected soon."

Gold Hill Target Area

The Gold Hill trench discovery, with grades up to 5,747 g/t silver equivalent (AgEq), is interpreted as a splay off the main Porcupine/Kinman structure which yielded 22,863 tons of historic production from the Comstock Mine, with average production grade of 1,240 g/t silver. The Gold Hill vein structures are thought to be transverse-type veins similar to the style along the Porcupine/Kinman vein structure. Transverse-style veins in the district, like this new vein discovery, are typically very high-grade silver and can support significant ore-shoots.

The Gold Hill trench was planned to follow up work conducted earlier in the season that identified a Pb-Zn soil anomaly. Upon intersecting the vein with trenching over approximately 8m, the trench was redirected to follow along the trace of the vein resulting in more than 20m of continuous exposure.

Bounty Target Areas

The Bounty target covers the northwest part of the Keno Summit area where a series of northeast trending structures are hosted in the Keno Hill quartzite and greenstones. Historic work has been conducted on the Buccaneer and Rum Tum vein structures, where some limited prospecting exposed the veins. In August 2017, sampling was undertaken by the Company as an initial investigation of the area as a potential target. Results of up to 12,078 g/t silver were obtained from surface sampling at the Buccaneer vein structure. Further grab samples from the Buccaneer vein showed high levels of silver, lead and zinc with elevated gold and copper.

These initial results were followed up with prospect scale mapping and trenching across the overburden covering the Buccaneer vein trend. Combined, the four trenches uncovered 70m of strike extent straddling the historic area of workings. Based on these results, further work is warranted in 2018 and is likely to consist of additional trenching and drill testing of the Buccaneer vein. Encouraging results were also received on the Rum Tum vein structure.

Additional 2017 Field Exploration Work

Soil sampling was conducted on the prioritized areas to test targets developed from known vein extensions, magnetic lineament studies and the extension of known anomalies from previous soil surveys. Soil samples were collected on eight targets including Silver Queen, Homestake, Bounty, Caribou, Faith, Vanguard, Duncan Creek and Vancouver. The surveys outlined significant anomalies in most of the target areas. These results have confirmed the value of soil sampling for developing new trenching and follow-up diamond drill targets at the Company's Keno Silver Project. Additional follow-up in these areas is planned for 2018.

Detailed satellite ortho-photos were also collected over the entire property during the year. One-metre contour data produced from the imagery will enhance the project survey control. Ground and airborne geophysical surveys were conducted along 129 line kilometres in the Homestake, Silver Queen and Caribou/Faith areas. Further geophysical work will be conducted in 2018 as part of additional work on the identified earlier-stage targets.

Quality Assurance / Quality Control

Analytical work in 2017 was done by Bureau Veritas Commodities Canada Ltd. with sample preparation in Whitehorse, Yukon and geochemical analysis in Vancouver, British Columbia. Each rock (grab) sample was analyzed for 36 elements using an Aqua Regia digestion with inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and inductively coupled Plasma-mass spectrometry (ICP-MS) (AQ202). Samples with over limit silver and gold were re-analyzed using a 30-gram fire assay fusion with a gravimetric finish (FA530-Ag, Au). Over-limit lead and zinc samples were analyzed by multi-acid digestion and atomic absorption spectrometry (MA404) or titration (GC516, GC8917). All results have passed the QAQC screening by the lab.
